Frederick tossed a number cube and then tossed a coin 100 times as part of an experiment. He recorded the number of times he tos
sed a six or tossed a number other than six, and the number of times the coin landed on heads or tails. The results are listed in the table below.
Based on these results, what was the probability that Frederick’s coin landed on tails after he tossed a six?
A.3/25
B. 31/100
C. 12/31
D. 69/100

A general linear equation is given by:
Where a is the slope and b is the y-intercept.
Here we will find that the linear equation that represents the situation is
And we can expect that the median salary in 2048 is $2.853 million
If the line passes through the points (x₁, y₁) and (x₂, y₂) then the slope can be written as:
Here we know that:
in 2007 (x = 7) the median player salary was y = $1.5 million
in 2013 (x = 13) the median player salary was y = $1.7 million.
Then we have two points that we can write as:
(7, 1.5)
(13, 1.7)
Note that the y-value is in millions.
Then the slope of the linear equation will be:
So the linear equation is something like:
To find the value of b, remember the point (7, 1.5), this means that when we have x = 7, we also have y = 1.5, then we can replace these in the above equation:
Then the linear equation is:
b) Now we want to predict the median salary in 2048. For 2048 the x-value is x = 48
So we just need to evaluate this in the linear equation:
Then the median salary in 2048 will be $2.853 million
